FoldraImage to PDF · Android
Photos into a clean PDF, entirely on your phone.
Pick your images, arrange the order, convert. Nothing is uploaded, nothing is watermarked, and there is no cap on how many pages you can add.
Genuinely offline
Your photos never leave the phone
Conversion never touches the internet. Images are decoded, rotated and written into the PDF entirely on your device. There is no account, no sign-up, no cloud storage and no server behind this app — it works on a plane, in a basement, on a train.

Questions
Foldra — frequently asked
Is Foldra free?
Yes. Converting images to PDF is free, with no watermark and no page limit. The free version is supported by ads, and a one-time in-app purchase removes them permanently — there is no subscription.
Does Foldra work offline?
Yes. Your images are read, rotated and written into the PDF entirely on your device, so conversion works in airplane mode. Internet access is only used to display ads and to verify the in-app purchase.
Does Foldra add a watermark to my PDF?
No. Every PDF comes out clean — no stamp in the corner, no "created with" footer, no page ceiling and no trial that expires.
Which image formats can Foldra convert?
JPG, JPEG, PNG, WebP and HEIC. You can combine any mix of them into one multi-page document, and orientation data is read from each file so portrait photos do not arrive sideways.
Are my photos uploaded anywhere?
No. Foldra has no account system and no server. Your images and the PDFs you create stay on your phone — we cannot see them, because there is nowhere for them to go.
